Anyone have any experience with the stage II system? That looks to be on sale on ebay for $4600.

[THATDONFC]

The stage 2 setup is really bitchin. Makes a lot of power, super reliable, very nice upgrade.

I'm so sad that I didn't have one of these on my e36 m3 before it got totaled. Now I have an e46 m3. Time for big powa!

Well what kind of power, they don't list many specs on the ebay auction.

[THATDONFC]

What motor? Tell me and I will shoot you some numbers.

[MR 325]

I need this!

[mbonder]

I've got an s50 swapped late model 325is. At this point the motor is stock, the exhaust is jacked, but I would be upgrading that with a FI application anyway.

I'm just wondering how this kit compares to others from AA, etc. I've heard that AA's customer service is miserable, so I'd like to find other options that may provide me with the know how to install in an e30.

Anyone on the boards installed one of these in their swapped car?

The Stage 1 system is rated at 369 HP - 310 HP at the wheels. This system comes complete with High Flow Injectors and RMS Software.

st 3 505 crank - 420 wheel.

The RMS kit doesn't really compare to AA. RMS makes the big power.

Here's a picture of an s50 swapped e30 with an RMS kit. The brackets are the old style though. RMS has a new bracket design.

RMS also has very very good tech support.

So my question is there gonna be issues with fitment? Everything for turnkey is included? Can we see some dyno charts?

Does this need 21 lb injectors?

Everything is included. Every bracket, nut, bolt. Software is included as well as 28.8 lb injectors. I'll be sure to get some dyno graphs.

Poopy for high comp pistons.

Alright, well the difference between stages I and II is that stage II has the aftercooler, what's the difference between stages II and III, performance wise, how is the extra power made? Also, what's the price difference?

Seems like about $1k difference between stages I and II, can the same difference be expected between II and III?

Is there a website to buy through rather than ebay that gets you the same price?

[M-technik-3]

Impeller pitch is different correct? Is this gonna be standard price or a limited time offer?

This kit is perfect for the stock compression pistons. If you raised the compression for an NA application then that's different.

You can buy directly from RMS by calling in but you will not get the same price as on eBay. Or maybe you will if you catch Osh on a good day. With the aftercooler it is safer to run higher boost. About 14 psi. Which makes for more power.

We do not have the stage 3 on the eBay store yet. I am not sure what it consists of yet. I'll ask tomorrow and find out. I believe it includes low comp pistons along with some other engine goodies. I will verify this tomorrow. I'll also get you a stage 3 price. I doubt the same difference can be expected between 2 and 3.

Impeller pitch is different correct? Is this gonna be standard price or a limited time offer?

We use the v2 s trim as a standard on both the stage 1 and 2 kits. They can be upgraded to t trim though. We are currently switching over to the v3 blowers. No oil feed or drain lines needed. Makes for an easier installation.
We have not yet decided if the price will stay the same. For now it is a limited time thing.

Thanks for all the great questions! Keep em comin.
